Numbers of H7 sequences associated with different NA subtypes, avian hosts, viral pathogenicities and years and locations of sampling are given in brackets. Note that it was not possible to determine such information for all sequences. For different avian host taxonomic orders, we use the abbreviations Ans. = Anseriformes, and Gal. = Galliformes.
